 **input([prompt])** #Where prompt is a string value

輸入()參數:

接受單個參數。無論用戶鍵入什麼，它都將作為輸入參數。

輸入()返回值

input()函數實際上是對輸入字符串進行求值，並嘗試將其作為 Python 代碼運行，輸出作為字符串返回。

| 投入 | 返回值 |
| 線 | 通過移除尾部換行符來創建字符串 |

Python 中input()方法的示例

示例 1:輸入()在 Python 中是如何工作的？

 # get input from user

inputString = input()

print('The inputted string is:', inputString) 

輸出:

Python is interesting.
The inputted string is: Python is interesting 

示例 2:通過提示獲取用戶輸入

 # get input from user

inputString = input('Enter a string:')

print('The inputted string is:', inputString) 

輸出:

Enter a string: Python is interesting.
The inputted string is: Python is interesting 

示例 3:輸入員工詳細信息

 # take three values from user
name = input("Enter Employee Name: ")
salary = input("Enter salary: ")
company = input("Enter Company name: ")

# Display all values on screen
print("\n")
print("Printing Employee Details")
print("Name", "Salary", "Company")
print(name, salary, company) 

輸出:

Enter Employee Name: Jessa
Enter salary: 8000
Enter Company name: Google

Printing Employee Details
Name Salary Company
Jessa 8000 Google 

示例 4:計算兩個輸入整數相加的程序

 # convert inout into int
first_number = int(input("Enter first number ")) sec second number "))

print("\n")
print("First Number:", first_number)
print("Second Number:", second_number)
sum1 = first_number + second_number
print("Addition of two number is: ", sum1) 

輸出:

Enter first number 28
Enter second number 12

First Number: 28
Second Number: 12
Addition of two number is:  40
